In the Eastern Wilderness, damage to the origin is basically incurable.
For instance, if one loses ten percent of their origin, even if their body recovers, a cultivator's spiritual power could only be restored to ninety percent.
The remaining ten percent would be irrecoverable.
Even if one's realm improved later on, and their spiritual power became stronger, the lost ten percent of the origin would never be regained.
Of course, it's not that there are absolutely no ways to deal with it.
Some precious heavenly and earthly treasures can repair the origin.
For example, the Three Lights Divine Water from Star Heaven Dao Sect is known to be omnipotent.
Another example is an alchemy recipe called "Sun Bathing" from the Sun Bathing Sea, which is specifically designed for situations of origin damage.
But for Xue Ting, both of these were precious items that were impossible to obtain.
